The Beam Saber Force is a force introduced in R-Type Final.
Red Laser: Crimson Beam - Droid Force swings laser sword in cutting motion hitting enemies in front while also shooting a v-shaped sword-beam projectile.
Blue Laser: Indigo Ray - Droid spins sword at a diagonal, while lasers fire off of sword tip at 45 degree angles.
Yellow Laser: Ochre Ray - Similar to Crimson Beam except there is a large energy ball on the tip of the sword that deals significant damage and the third swing is far wider, even reaching enemies lightly behind the fighter.
